The choice of towel

You want to replace your iron, heated towel rail shabby for something modern, beautiful and functional. So all the towel, or as they are also called design radiators are divided into water, electrical and combined. What is the design of radiators, we think, to explain to anyone not necessary - the name speaks for itself. This is perhaps the most beautiful space heaters of all. Distinguished by their wide variety of shapes and colors. Their appearance in the Western market is primarily due to the increasing level of requirements for the registration of apartments and offices both in aesthetics and in comfort. As a result, and there was a need for heating devices that would constitute a simultaneous interior elements. The main producers of such appliances - Arbonia, Zehnder, Kermi. In Europe, we can count two dozen companies producing similar products. In Russia we design radiators sold quite a long time, but such broad applications, such as in the west, they have not received. The urgent need for such heating devices Russians feel so far only in the bathrooms. And even its name was given designer radiators - towel warmers. By analogy with the domestic U-shaped radiator, installed many years is in our bathrooms. And now, a person receives a new home, look in the bathroom to have nabivshuyu nauseam arc protruding from the wall and thinks: Yeah, I'm in an old house for many years seen. Must be on something better to replace! And takes an interest in ways to solve this seemingly simple question at first glance. Which designer radiators offers the buyer a modern market? The modern market offers a huge selection. Choosing Import towel should be borne in mind that designed most of them on their western operating conditions. Post, at least from what we have established a towel in hot water systems (DHW). Do not be surprised Russia Towel connect only to the DHW, and not to the heating system, as in the rest of the world. This is another feature of our national system of heating. And who is in the DHW will provide specific training of water? And is used for the manufacture of these devices does unprotected against corrosion a thin-walled steel (1-1,25 mm). And because in our conditions, these devices do not last long - a term of one and a half months, until one and a half years (the unit served for 3 years is just a record). And the wonderful (design) space heater that has a fairly large value (from 0 to 00 !!!), account after this period, as it does not hurt, throw in the trash. Repair it will not be reimbursed. And thrown almost 100% of the installed devices. Oh well if only the device itself had to be replaced. After the flood has changed yet, and parquet floors, ceilings and wallpaper. And part of the furniture. And not only in his native house, and neighbors. And it already smells are not two hundred dollars. And this is the main reason that Western designer radiators in the eyes of domestic consumers themselves actually discredited. As a result, supply of imported design radiators in Russia almost completely stopped. If such radiators are delivered, then they have written in large letters: Only for heating systems. That is, for those systems where the parameters of the coolant is more or less acceptable to western instruments (although in reality these conditions are acceptable and can be called a stretch). And what are the ways to address this issue? There are two ways. The first of them - make towel, designed exactly to our terms of use. The first attempt to design and manufacture of bathroom towel warmer, adapted to our conditions, was made by TIME in cooperation with the plant KZTO (Tver). Went on a simple way - to increase the pipe wall thickness, as well as the application of internal anticorrosion coating of polymeric material. This design allows us to solve two problems: first - the fight against corrosion, the second - to prevent the accumulation of corrosion products in the towel. Since there have been several series of heated towel rails. By design, these towel warmers are not inferior to the best European standards and the reliability and durability substantially exceed them. This model heated towel rails - Radiator in a vertical design: "note-18", "SKETCH-9", "SKETCH-18," Etude -24 "," LIRA ". Production Company TVEK released its model TVEK-PS-2P. Created several series of heated towel rails proved to be very good. However, creating a new series of heated towel rails, we clearly understand that this path (increase in wall thickness and corrosion treatment inside the radiator) will sooner or later lead to a very high price of the product. Metal always more expensive. The technology works with a thick-walled pipe is in itself more expensive than thin-walled. Polymer coating on the inner surface also is not cheap. And hence, the path of this impasse. The more that the West had long been laid out on the shelves - they have passed this way too, but it never came. Therefore, an attempt was made to solve the problem on the other hand - create a heat exchanger - a towel. More precisely, this problem is to divide the system into two circuits: one remains in the system of hot water, the second - the most vulnerable (which includes a towel) - from the domestic hot water output and thus prolong its life. The problem was to make the heat exchanger is sufficiently effective, maintenance-free, highly reliable and, importantly, affordable. But this should not be universal, and a specialized heat exchanger, that is intended only for use with towel. It was his of specialization and has helped to solve the problem. This heat exchanger has been created. And even got its own name - TVEK. True, we often call it not a heat exchanger, and the adapter. That is the device, allowing towel to adapt to our conditions of operation. On the first contour, which represents the inner surface of seamless steel pipes, hot water circulating system tank. The second circuit provides a natural gravity circulation of coolant in the radiator design. Moreover, the construction of a small volume of the adapter provides a highly efficient circulation in the second circuit. The average temperature in the towel warmer, as is known, is determined by water temperature at the inlet, heat exchanger and heated towel rail, and pipeline construction. In our case, with nominal power towel around 600 watts, the length of the pipe not more than 3 meters from the adapter to the towel warmer at a temperature in the hot water - 65 ? C, heated towel rail reaches an average temperature of 55 ? C in 15-20 minutes of operation. An increase in the length of the pipe 1 meter will reduce the average temperature of less than 1 degree. It's also not scary. The average temperature in the towel warmer you'll get to 10 ? C below the temperature of water in the tank. And in the bathroom as a result will not be cold? Rather the contrary. The area of ??a standard U-shaped towel warmer is extremely small (that's why for its heating and water is used with high temperature). You and I have replaced a small U-bend on a towel with a large branched surface. And, therefore, heat will be released in the air so much more. Still have to install the valve that limits the flow of coolant. How reliable is such a device? Thermal tests conducted at the Research Institute SANITARY prove the absolute performance of the system. With regard to strength and, consequently, the reliability of the adapter, then it is determined primarily by the construction of the first circuit heat exchanger to be connected directly to the DHW. And this path is made of thick-walled seamless steel pipe, the reliability of which has been proved repeatedly in a variety of products (including heated towel rail, installed in our bathrooms at serial construction). It depends only on the quality of the original pipe. So if you use a good pipe, let out a good manufacturer, we doubt the strength characteristics is simply not necessary. And 20-30 years of this adapter is guaranteed. This is confirmed by tests that the adapter TVEK now been successfully completed. Application of technical solutions are patented. As far as the use of adapters increases the cost of construction? Installing the adapter udorozhit system is not much. Basically, the cost of the adapter itself and the cost of its installation into the system. Thus, the rise in the cost of the system is possible in the range of 5-10%. But the system with the adapter is visible at first sight, but a very big advantage, which justifies such a price increase. If before, paving the pipeline, you had to take into account the pressure in the system, and the presence in the water system hot water of oxygen, and the possibility of water hammer, etc. and because the pipeline had to be sufficiently tough and durable, then using an adapter rigid pipe is required only in the first loop. In the second loop you can use any tube - plastic and metal, flexible, etc. (This, incidentally, also gives some additional possibilities for design). And in such a system simply can not be of major accidents. If you have filled in an excess amount of fluid in the second circuit, then heated it does not tear, as standing in it simply a safety valve to dump excess water program. And even if for some reason, burst pipe underwater towel, your neighbors do not even notice - the amount of coolant in the second loop system is only a few liters. It's not 50 cubic meters of hot water that are emitted into the apartment when the accident supply ducts in the existing system available today. Now with factory Kermi preparing to release a whole family of design-radiators with a heat exchanger TVEK, which soon will be available. Real working life of the system will be at least 20 - 30 years old. Besides the problem of strength and corrosion of equipment for hot water (DHW) is actively overgrowing the inner section of pipe deposits sometimes up to complete overlap kanalov.Pri use of heat exchangers, this problem is easily solved by cleaning the coolant heat exchanger or replace it. Naturally, such a procedure is much cheaper than replacing the very design of the radiator. Electric Towel good in three cases: First, if you make major repairs Secondly, if there is no desire to intrude into the existing water supply system Third, if you want to hang another towel Furthermore, we should not forget about the long summer trips of hot water. Electric heated towel rack is easy to install and connect without the grandiose reworking of all pipes in the apartment. When you install an electric towel warmer should exactly follow the rules and recommendations of the SEP. The choice of electric towel rails in the company of TIME is quite wide. Virtually all Russian Water Towel ETUDE, LIRA produced in an electric performance. Particularly wide range of electric towel rails (design-radiators) German firm ZEHNDER. They all have a programmer that allows you to specify comfortable living conditions. In design - Radiator ARBONIA adjustment - manual.
